OBS Studio is a free, open source application which allows video recording and live streaming, available for Linux, Windows and Mac OS X.

The application is popular among game streamers, being used to stream to various popular websites such as Twitch.tv, YouTube, Hitbox.tv, Vaughn Live / iNSTAGIB.tv, DailyMotion, Connectcast.tv, GoodGame.ru, CyberGame.tv, CashPlay.tv along with custom streaming servers.

Among the changes in the latest OBS Studio 0.14.0 / 0.14.1 are:

added deinterlacing. Deinterlacing modes can now be used by right-clicking the source and going to "deinterlacing" in the menu to select the deinterlacing options. Deinterlacing only works on sources that support it (video capture device source and media source primarily);

added full NVIDIA NVENC encoder. NVENC is supported for windows and linux, and can be used via the simple output mode. (Note: To use NVENC on linux, you must compile or get a version of FFmpeg with NVENC support);

added alt-cropping (cropping via the alt-key). This type of crop only affects the specific scene item and does not affect all instances of a source. You can also change the specific crop number values in the source transform dialog;
